Pristimantis thyellus

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Pristimantis thyellus faces severe threats from ongoing deforestation and agricultural expansion within its extremely limited range in the Cordillera Oriental of Colombia. The species' restriction to high-elevation cloud forests makes it particularly vulnerable to climate change impacts, as warming temperatures force suitable habitat upslope with nowhere left to retreat. Mining activities and infrastructure development in the region pose additional pressures on the remaining forest fragments where this endemic frog persists.

Threat summary

Habitat

This species inhabits montane cloud forests and elfin forests at elevations between 2,800-3,200 meters in the Cordillera Oriental of Colombia. It requires pristine forest conditions with high humidity and stable temperatures typical of these high-altitude ecosystems.
